Trouble Defining Multiple InfluxDB Servers

[nhproject]

In the [influxdb] section in the configuration file, there's the "urls" variable. I tried to define over there three influxdb machines which I have in my cluster, like this:
urls = ["SERVER1_URL","SERVER2_URL","SERVER3_URL"].
After that, I restarted the Kapacitor in order to apply it - but nothing happened, it seemed like its stuck, and the log didn't showed the usual messages it always shows.
What can be the reason for that? Should I write the servers in a different way?

[nathanielc]

This looks correct to me. Are there any logs at all or does the process just hang when trying to connect?

[nhproject]

tail -f /var/log/kapacitor/kapacitor.log - no logs at all.

@nhproject can you check /var/log/kapacitor/kapacitor.err ? If Kapacitor crashes before it can initialize its logs, the STDERR content gets put there.

I've encountered this same issue when attempting to specify three 0.9.6.1 nodes in the config (not sure if it's 0.9-specific).

[nathanielc]

I was looking into this an it turns out to be a bug in the config parser. Should be fixed with #155

[nhproject]

thanks Nat!

[nathanielc]

Fixed with #268
